Title: Apparatus for testing the internal diameter of annular objects
IPC: G01B5/08
Filed: 1946-01-15
Abstract: 606,453. Linear-dimension gauges. HERBERT, Ltd., A., and CURSON, T. Jan. 15, 1946, No. 1318. [Class 106 (ii)] A linear-dimension gauge for comparing the internal diameter of a ring gauge with a standard of the type in which the test piece is placed on a rectilinearly movable table and in which movable jaws are provided on opposite sides of the table, said jaws being spring biassed into the gauging position is characterised in that the jaws are carried by carriages mounted on their supports through balls guiding them for rectilinear movement and in which quickacting means are provided for moving the jaws slightly against their spring bias to prevent fouling of the test piece during movement of the table to and from the gauging position. The gauge comprises a base 11, Fig. 1, which carries, on opposite sides of a vertically movable and tiltable table 12, two slides 18, each of which co-operates with an optical indicating device 19 of known kind. Each slide 18 also co-operates with a carriage 22 which carries a jaw 41 having a gauging point 23. Each carriage 22, Fig. 2, is carried by a member 18a rigid with the slide 18 and is vertically located by balls 27 riding in channels 26, formed by ridges 25 on the member 18a entering recesses 24 in the slides 22. Each ball 27 moves between two stops 28 as shown. Locating bars 30 secured to the underside of each carriage 22 project under the ridges 25 and co-operate with balls 32 to locate the carriage laterally. The balls 32 are located in bays 33, Fig. 3, and each carriage is urged in the gauging direction by a spring 34. A shaft 35 passes through each carriage and is provided with a finger 36 which co-operates with the carriage 22 in such a manner that rotation of the shaft 35 by turning a handle 43 thereon causes the finger 36 to move the carriage 22 slightly in the direction of the arrow A to allow the test piece to be placed in or removed from the gauging position without fouling the contact pieces of the jaws.

Title: Higher fatty acid esters of dextran
IPC: C08B37/02
Filed: 1958-01-16
Abstract: Dextran palmitate is made by heating dextran to 100 DEG C. to 155 DEG C. with a palmitic acid halide, preferably the chloride, in the presence of equal parts by weight of an acid acceptor and of a substance capable of dissolving or swelling the ester as it is formed, so as to produce a dextran palmitate containing 2,9 palmitoyl radicals per anhydroglucose unit.  The acid acceptor may be an organic base such as quinoline, pyridine or N-methyl morpholine.  The substance which dissolves or swells the ester may be xylene, toluene or dioxane.  The temperature employed and the reaction time depend on the boiling point of the mixture of acid acceptor and solvent.  Using a mixture of pyridine and toluene, a temperature of 100 DEG  to 115 DEG  C. is used for 1 to 3 hours.  With quinoline and xylene, a temperature of 150-155 DEG  C. is used for 30 minutes to an hour. The dextran employed may be native dextran produced microbiologically from sucrose, or it may be a dextran hydrolyzate having an average molecular weight of 60,000 to 80,000.  A composition of the ester in an organic solvent may be used to form chemical gloves.  The esters are soluble in non-polar solvents such as halogenated hydrocarbons, benzene, toluene and the xylenes, and a film of the ester deposited on the hands from a solution in an organic solvent is not removed by water, soap and water or abrasives.

Title: The manufacture of the dichlorohydrins of 4-vinylcyclohexene
Filed: 1948-01-19
Abstract: The dichlorohydrins of 4-vinylcyclohexene are prepared by treating 4-vinylcyclohexene with hypochlorous acid in an aqueous medium.  This may be performed by adding the acid to a dispersion of the olefin in water until a slight excess is present, or the hypochlorous acid may be prepared in situ by action of an acid on a hypochlorite.  In some cases the mono-chlorohydrin separates as an oil, and in this case a solvent, e.g. ethylene dichloride, is added and further reaction occurs to give the di-compound.  It is preferred to use a hypochlorite concentration of about 5.5 per cent, and a temperature of 10 DEG  C. or lower.  The product may be extracted with solvents. The Specification as open to inspection under Sect. 91 comprises also the preparation of 4-vinylcyclohexene dioxide by further treatment of the dichlorohydrin with alkali.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in pump priming mechanism
IPC: F04D9/00
Filed: 1931-01-17
Abstract: 366,695. Pumps. LEWIS, C. S., 2207, Pine Street, St. Louis, Missouri, U.S.A. Jan. 17, 1931, No. 1641. [Class 102 (i).] In priming apparatus for pumps two chambers are employed, the lower of which holds a charge of liquid for withdrawal by the pump, and means are also connected between the lower chamber and the pump intake so that liquid passes to the pump intake by gravity simultaneously with the withdrawal of a charge of liquid from the chamber. The intake C of the pump D communicates with the chamber B, which is also in communication with the sump L by pipes I, I<1>, I<2>. A small receptacle K open at its upper side is arranged in the chamber B and is connected by a downwardly sloping duct M to the intake C ; this duct M is connected by a pipe S to the horizontal portion I<1> of the suction pipe. The upper chamber A is connected by a pipe R to the intake C, and by a pipe N controlled by a valve N<1> to the lower chamber B. The pump outlet pipe E and suction pipe are joined by a pipe O with a controlling valve O<1>, and the discharge pipe F from the chamber A has a check valve G. Before the pump D is started, liquid is introduced through the pipe P to fill the pump, the chambers, and their associated pipes, including the vertical portion 1<2> of the suction pipe, up to the valve G. The expelled air passes upwards through the valve G. The pump is then set in motion and withdraws the charge of liquid from the chamber B ; this charge is forced through the pipe E into the chamber A, so that a quantity of liquid is forced from the chamber A into the discharge pipe F. Some liquid also passes into the chamber B through the pipe O, and through the pipe N. The liquid from the sump L rises in the pipe I to a height dependent on the reduced pressure in the chamber B. During this period of the working, liquid drains from the receptacle K' into the pump intake C, and any gas escapes from the chamber B through the parts K, M into the upper part of the intake C so that the pump is airbound. The connections M, C, E, O, I<2> permit the pressures in the two chambers A,B to be equalized and the chamber B will be filled by gravitational flow from the chamber A. During this filling action, gas is driven from the chamber B through the pipes M, S, to the chamber A, and also through the pipes I<2>, O. At this stage the pump is filled with liquid and acts to withdraw the second charge from the chamber B, so causing the liquid to rise higher in the pipe I from the sump L. The discharge of liquid from the pipe E into the chamber A compresses the gas in the chamber until the pressure is sufficient to cause the valve G to open for discharge. The action of the pump continues until the receptacle K is completely emptied of liquid ; the end of the pipe O in the discharge pipe E is then freed from liquid and the pressures in the chambers A, B are again equalized. The cycle of operations is then repeated until the remainder of the gas is expelled, and liquid is supplied continuously to the pump.

Filed: 1940-01-31
Abstract: 538,444. Centrifugal separators. SCHUTTE, A. H. Jan. 31, 1940, No. 1943. Convention date, Feb. 25, 1939. [Class 23] [Also in Group III] A slurry is filtered continuously in a centrifugal filter to which it is fed through the pipe 20, and the deposited cake is moved upwards by volumetric displacement so that it is continuously discharged over the lip of the rotary basket 36 while the liquid passes through the filter and is collected by the casing. The arrangement is described particularly in regard to the separation of a waxeous mixture which is carried in a steam jacketed tank 10. This mixture is supplied, together with water from the jacketed tank 12, to the pump 14 in which an emulsion is formed and passed to the mixer 15. Here it is mixed with regulated quantities of air supplied through the pipe 16 and the resulting emulsion is pumped through the relief valve 18 and the pipe 20 to the bottom of the perforated basket 36. Temperature control of the emulsion is obtained by the introduction of cold water through the pipe 19. The separator is jacketed and beating water or steam is supplied through the pipes 28, 29 to the upper and lower parts of the jacket. These fluids may also be supplied by the pipe 34 to heat the cake removing channel 33. A partition 42 divides the casing into two sections for the reception of the filtrate. The feed to the machine is continuous and consists of solidified wax, liquid wax and water. The deposited wax cake is moved up the basket and overflows the basket lip to be collected in the tank 52. If it is not desired to melt the cake, it can be removed by mechanical or other means. The intermediate wax will mostly be discharged through the upper part of the basket and collected in the tank 46, while the filtrate from the lower part of the basket passes to the tank 38. The intermediate wax from the tank 46 can be treated again in a similar fashion and is passed through two machines, the filtrate from the second machine being brought back and fed to the first machine at a point above the normal wax feed. Specification 526,744 is referred to.

Title: Method and apparatus for the transmission of intelligence
Inventor: LENDER ADAM

Filed: 1965-01-15
Abstract: 1,041,765. Data transmission. AUTOMATIC ELECTRIC LABORATORIES Inc. Jan. 15, 1965 [Jan. 17, 1964; Feb. 4, 1964; Feb. 13. 1964 (2)], No. 1944/65. Heading H4P. Binary signals are converted, prior to transmission, to a multi-level signal and reconverted at the receiver. In the conversion the input binary signal is first converted to an intermediate binary signal, in which each bit is a combination of the present input bit and a preset number of preceding bits of the intermediate signal, and then the intermediate signal is converted to the multilevel signal, in which each level is derived as a combination of the present intermediate bit and the same preset number of preceding bits of the intermediate signal. In a first embodiment, Fig. 2 (not shown), the binary input feeds a modulo-2 gate whose output feeds a 4-stage shift register. By returning the outputs of the first three stages to the gate, the intermediate signal appears at the output of the gate. All four stages feed an adder which provides a 5 level signal for transmission. The receiver may comprise two rectifiers in series followed by a squaring circuit, or five slicing circuits, one for each level, which feed a modulo-2 gate followed by a toggle. A second embodiment. Fig. 5 (not shown), derives a multilevel signal which may take both negative and positive values. The arrangement is similar to that already described but the last two stages of the register pass to the adder via inverters. A further embodiment uses a combination of phase-shift and multi-level signalling: the transmitted signal comprises signals of 0 and # phase and of zero, half, or full amplitude. In the example described with reference to Fig. 9 (not shown) the phase indicates the predominating marking of the previous four bits of the input binary signal, and the amplitude indicates whether four or three of those bits have that marking. Zero amplitude indicates that two are 1 bits and two are 0 bits. The multi-level conversion may be checked for errors by the arrangement of Fig. 12 (not shown), which is fed by both the multi-level signal and the corresponding binary signal.
